Matcha Supply Chain Partner | 5kg - 100t | Matcha sourcing Expert

As a TOP RATED PLUS consultant and one of the leading matcha sourcing experts on Upwork, I specialize in one thing: building world-class Japanese matcha supply chains for ambitious international brands. Finding a reliable, high-quality supplier in Japan's hyper-competitive market is the single biggest challenge for global brands. I solve this problem. Based in Tokyo, I am your strategic partner on the ground. My background is unique: with over a decade of experience as 10+ years in corporate finance and strategic planning at a major Japanese national news organization, I bring expert-level investigation, analysis, and high-level communication skills to every project. This allows me to uncover producers and build the critical relationships that are inaccessible through simple online searches. My service is a complete, end-to-end solution for your brand's foundation: * Strategic Sourcing & Market Analysis: Identifying the right producers who align with your brand's quality, volume, and budget. * Supplier Vetting & Quality Assurance: Ensuring certifications, product quality, and export-readiness meet your exact standards. * Bilingual Negotiation & Relationship Management: Handling all communications in Japanese to secure the best possible terms and build strong, long-term partnerships. * Logistics & Export Coordination: Managing the entire process from placing the order to final shipment. My 100% Job Success Score and history of successful, high-value matcha sourcing projects (as detailed in my portfolio) are your guarantee of a professional, results-driven process. If you are serious about building an authentic and profitable matcha brand, you need a true partner in Japan. Let's discuss how I can build the supply chain that will become the foundation of your success.
